(CBS/AP) Perhaps Facebook is an addiction after all. A California yoga instructor learned that hard way that you can't comes between one student and her social network.

Alice Van Ness, who was hired to teach hour-long yoga sessions at Facebook's Menlo Park campus, has been fired for her disapproving stink-eye glare at a Facebook employee using a cellphone in class.

Van Ness says she tells students before class to turn off their cellphones. But a female employee pulled out her cellphone in the middle of a Monday session and began texting.

The San Jose Mercury News says Van Ness didn't say anything, but she gave the student what she calls a look of disapproval.

"We're not talking about the U.S. government here," Van Ness told the San Francisco Chronicle. "We're not talking about Russia is about to bomb us. We're talking about Facebook. Something can't wait half an hour?"

The student later complained and Van Ness was fired by Plus One Health Management. The termination letter says Van Ness "made a spectacle" of the student.
